Panera Bread – Morgan Stanley downgraded the restaurant chain's shares to "equal weight" from "overweight", saying Panera may be losing its historical ability to continue to drive same-store sales higher. The firm said investors may find more value in Chipotle Mexican Grill, which was upgraded to "overweight" from "equal weight".

Colgate-Palmolive– Morgan Stanley upgraded the consumer product company's shares to "overweight" from "equal weight", on expectations of sales growth superior to that of its peers.

BlackBerry – Bernstein upgraded the smart phone maker's shares to "market perform" from "underperform", saying any lack of credibility about the Fairfax takeover bid is now priced into the stock, and that there's a better than 50 percent chance it will succeed.

Boeing - Budget carrier Norwegian Air grounded a new and is demanding that Boeing perform repairs. Norwegian said the jet needs fixing after less than 30 days in service.
